Answer:
Side-Side-Side SSS
Step-by-step explanation:
i could be wrong.. but thats the rule that proves triangles are congruent
see attachment
the required equation will be:
-5( 7w+ 8)= 30
-35w- 40= 30
-35w= 30+ 40( as 40 is taken to the other side, its symbol changes)
-35w= 70
W= 70/-35
W= -2
3(x+x+1)
hope this helps
